GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No.'2'70,079, dated January 2, 1 883,

1 Application filed September6,1882. (No model.)

To all whom it may concern Be it known'that I, PETER KELLER, a citi- W zen of the United States, residing at New Fig. 2 is'a similarisection, showing some of.

the parts in side view. Fig. 3 is a plan or top view. Fig. 1 is a cross-section on the linezrw,

Fig. 2. Fig. 5 is a cross-section of the valveseat. Fig. 6 shows the invention applied to a burner. 1

Similar letters indicate corresponding parts. The letter A designates a shell, which is pro- 2 5 vided with an internalscrew-thread, I), extending upward or inward from its lower edge, to which thread is fitted a screw-ring, 0, having cast or otherwise formed on its inner edge a nozzle, D, projecting in an upward direction.

0 At thejunction of this nozzle with the ring 0 are formed holes 0, which are inclined in an inward and lower direction, while in the side of the nozzle between its upper and lower edges are formed holes f. e

3 5 The letter G designates a valve of invertedcup shape, which is fitted on the nozzle D, and provided with openings t in its side, such openings being elongatedto the shape of slots. Under normal conditions the valve G rests on 40 the ring 0, and its openings 41 are situated opposite to the holes f of the nozzle D, so that the gas admitted to the nozzle can escape freely in an upward direction, while when the pressure of the gas rises to a sufiicient degree 5 to raise the valve the openings '5 are brought above the escape-holes f, and the latter are partially closed by the valve. The valve G is weighted to resist the upward pressure of the gas, and it is guided in its vertical movement by a stem, k, passing through a bridge, I, cast to the shell, while the upward move ment of.-the valve is determined by a hub, 02, arranged thereon to strike against the bridge.

In case any of the gas fiowiug'thro'ngh the apparatus should condense, theproductofsuch 5 5 condensation ispermitted to escape through theinclined holes 6, so that the working of the valve is not liable to be interfered with thereby, the position of said holes being important to the attainment ofthis object. By the shape of the valve-opening ithe gas-escape holes f are exposed to the fullest extent, andare least liable to be covered by the valve in case the latter should turn by accident to present a solid portiouthereofto said holes, so that when 6 the gas is at or below the normal pressure-the flow remains uninterrupted, The extent or height of thescrew-threatl bis greater than the width ofthe screw-ring (J, and the position of this ring is at the upper part of the thread, so that a portion of said thread is left free below the ring for the reception of the coupling whereby the shell is joined to the gas pipe or meter at the lower end.

When my invention is applied to a regulator for attachment to gas-meters the shell A is provided with an external screw-thread. b,'at. the upper end, as shown in Figs. 1 to 4; but

when it is applied to gasburners such thread is omitted, a tip being inserted in the upper end of the shell in the usual manner A gas-regulator has heretofore been provided with an interior plug having inclined orifices formedin its vertical wall for the purpose of permitting the escape of condensed vapor resulting from the passing gas, andin another form of regulator an interior nipple has been provided with a cup-shaped valve having a horizontal slot in its vertical wall to register with lateral perforations in the nipple. Such features of themselves are not therefore broadly claimed by me, as my invention comprises a novel combination of devices which 7 provides a very efficient and desirable gas-regulator, capable of performing all the essential 5 functions ofa gasbu-rner in a satisfactory manner.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, substantially as hereinrco before set forth, of a shell having the internal screw-thread extending upward from its lower edge, the screw-ring adapted to said thread and formed withthe upwardly-projecting nozzle having the inclined. water-escape holes at itsjunction with the ring and the gas-escape holes in the side thereof, the inverted-cupshaped valve fitted on thenozzle and provided with the elongated openings, which are situated opposite to the gas-escape holes of the nozzle under normal conditions, and which are [0 brought above said holes when the valve is raised by the pressure of the gas, for the pur- PETER KELLER.
